Two 1.50-V batteries—with their positive terminals in the same direction—are inserted in series into the barrel of a flashlight. One battery has an internal resistance of 0.340 Ω, the other an internal resistance of 0.170 Ω. When the switch is closed, a current of 600 mA occurs in the lamp.
(a) What is the bulb's resistance?
(b) What fraction of the chemical energy transformed appears as internal energy in the batteries?

A typical small flashlight contains two batteries, each having an emf of 1.50 V connected in series with a bulb having a resistance of 18 Ω . A. If the internal resistance of the batteries is negligible, what power is delivered to the bulb? P = B. If the batteries last for a time of 4.1 h , what is the total energy delivered to the bulb? W = C. The resistance of real batteries increases as they run down....
